TECHNICAL FIELD

The present disclosure relates generally to remote control of a machineand, more particularly, relates to a remote operation of machines usedin mining, earth moving, or the like.

BACKGROUND

Many machines used in the earth-moving, construction, mining, andagricultural industries operate in challenging environments. Forexample, some mining machines operate in underground mines where theenvironment may be more challenging due to low tunnel clearances andground stability concerns surrounding the immediate area. In recentefforts to improve safety at such worksite environments, trends havebeen to reduce the number of on-site operators at these worksites byimplementing machines that are remotely controlled from a remoteoperator station (ROS).

For machines employed at the physical worksite, the ROS may bepositioned remote from the machine at a safer location at or near theworksite or may be away from the worksite. For example, the ROS may bepositioned indoors in an office environment.

U.S. Pat. No. 6,633,800 (the '800 patent) discloses an apparatus andmethod for a control unit that allows for autonomous, manual andtele-operation of mining vehicles. The control unit allow atele-operator, in a remote tele-operator station, to use image andoperational data, joysticks and foot pedals to remotely control themining vehicle. While beneficial, a better control system is needed.

The Ethernet LAN 128 may include a plurality ofcommunication channels 204, the local router 162, a first switch 206 anda second switch 208. In one embodiment, the Ethernet LAN 128 may operateat 100 base-T.

The local router 162 is disposed on the machine 100 and includes a localrouter processor 210. The local router 162 is in operable communicationvia communication channels 204 (of the Ethernet LAN 128) with the localtransceiver 126, the first switch 206, the RSM 138 and the second switch208. The local router 162 is also in operable communication with theAECM 134 and the environment monitoring system 136 via the first switch206 and the communication channels 204. The local router 162 is inoperable communication with the machine ECM 172, the service port 140,the first display 146 and the positioning system 150 via the secondswitch 208 and the communication channels 204.

The local router 162 is configured to manage data traffic on theEthernet LAN 128 and to convert serial data to Ethernet InternetProtocol (IP)/Transmission Control Protocol (TCP) packets and viceversa. Such conversion allows serial data from third party systems to beaccessed on the Ethernet LAN 128.

The local router 162 is configured to receive the control signals/safetysignals, generated by either the ROS ECM 186 (FIG. 3) or the AISMonitoring System 166, from the local transceiver 126 (FIG. 2) and totransmit such control/safety signals via the communication channels 204to the AECM 134. The local router 162 also receives input control orsafety signals from the RSM 138. The local router 162 receives data fromthe AECM 134 and from the environment monitoring system 136 (e.g., videodata, audio data, and positional and distance measurement information)via the first switch 206. The local router 162 receives data from one ormore Vehicle ECMs 124, the service port 140, the first display 146, theVHUS 148 and the positioning system 150 via the second switch 208.

The first switch 206 is disposed on the machine 100 and is in operablecommunication with at least the local router 162, the environmentmonitoring system 136 (IP cameras 198, microphone 200 and LADARs 202)and the AECM 134 via the communication channels 204 of the Ethernet LAN128. The first switch 206 is configured to transmit and receive controlsignals/safety signals from the local router 162, and data from, atleast, the environment monitoring system 136 and the AECM 134. The firstswitch 206 is configured to transmit data only to the one or moredevices for which the message was intended. Furthermore, the firstswitch 206 has Dynamic Host Configuration Protocol (DHCP) addressassignment which allows devices, for example the IP cameras 198, to befitted or replaced without manually configuring static IP addresses.DHCP is a standardized network protocol used for dynamicallydistributing network configuration parameters, such as IP addresses,reducing the need for a user to configure such parameters manually. Thesecond switch 208 is disposed on the machine 100 and is in operablecommunication with the machine ECM 172 via the communication channels204 of the Ethernet LAN 128.

The plurality of communication channels 204 are configured to transfercontrol signals/safety control signals or data between two points, forexample, between devices connected to the communication channels 204. Inaddition to that described above, at least one communication channel 204is disposed between the machine ECM 172 and the transmission ECM 174 andanother communication channel 204 is also disposed between thetransmission ECM 174 and the implement ECM 176. The first display 146may also be in communication with the VHUS 148 (including any associatedwireless interface for the VHUS 148) via one of the communicationchannels 204 of the Ethernet LAN 128.

The first CAN 130 is disposed on the machine 100 and enables operativecommunication between the AECM 134, the machine ECM 172, thetransmission ECM 174, the implement ECM 176, the service port 140, theengine ECM 178, the aftertreatment ECM 180, the first display 146, theHVAC ECM 182, the VHUS 148, and the TMS transceiver 218.

The second CAN 132 is disposed on the machine 100. The second CAN 132includes a plurality of segments 214. The first segment 214 a of theplurality enables operative communication between the AECM 134, themachine ECM 172, the LOS transceiver(s) 160, a first IMU 154 and asecond IMU 156. The second segment 214 b enables operative communicationbetween the engine ECM 178 and the aftertreatment ECM 180. The thirdsegment 214 c enables operative communication between the keypad 158,the transmission ECM 174, the implement ECM 176 and the first display146.

The DL 142 is disposed on the machine 100. The machine ECM 172, thetransmission ECM 174, the implement ECM 176, the service port 140, theengine ECM 178 and the aftertreatment ECM 180, the local router 162 andthe VHUS 148 are in operative communication via the DL 142.

The AECM 134 is disposed on the machine 100. The AECM 134 includes aprocessor 188 g which may be implemented by one or more microprocessorsor other processors well-known in the art. The processor 188 g includesa local memory 190 g and is in communication with a read-only memory 192g and a random access memory 194 g via a bus 196 g. The random accessmemory 194 g may be implemented by Synchronous Dynamic Random AccessMemory (SDRAM), Dynamic Random Access Memory (DRAM), RAMBUS DynamicRandom Access memory (RDRAM) and/or any other type of random accessmemory device. The read-only memory 192 g may be implemented by a harddrive, flash memory and/or any other desired type of memory device. Theprocessor 188 g is configured to execute machine-readable instructionsand to generate (output) control signals, based on received (input)control signals, to control operation of the machine 100 and one or moreof the Vehicle ECMs 124. Such machine-readable instructions may be readinto or incorporated into a machine-readable medium such as, forexample, the local memory 190 g. In alternative embodiments, hard wiredcircuitry may be used in place of, or in combination with,machine-readable instructions to implement a control method for themachine 100.

The AECM 134 is in operable communication with the environmentmonitoring system 136 and the local router 162 via the first switch 206and communication channels 204. Furthermore, as shown in FIG. 2, theAECM 134 is in operable communication with the RSM 138, the localtransceiver 126, one or more Vehicle ECMs 124, the service port 140, thefirst display 146, the positioning system 150 and the VHUS 148 via theEthernet LAN 128.

In addition, the AECM 134 is in operable communication with the VehicleECMs 124, the service port 140, the first display 146, VHUS 148 and theTMS transceiver 218 via the first CAN 130. The AECM 134 is also inoperable communication with the machine ECM 124, the first IMU 154, thesecond IMU 156, the LOS operator console 184 and associated LOStransceiver 160, via one or more segments 214 of the second CAN 132.

The AECM 134 is configured to receive the control signals and data viathe local router 162 and/or the first switch 206. The AECM 134 may alsoreceive control signals from the service port 140. The control signalsmay be generated by the ROS ECM 186 (FIG. 3), the AIS Monitoring System166 or the keypad 158.

The AECM 134 is further configured to process the control signals anddata. The AECM 134 is configured to generate (output) control signalsbased on the processed control signals and data, and to transmit suchcontrol signals to the environment monitoring system 136, the firstdisplay 146 or one or more of the Vehicle ECMs 124, wherein the controlsignals control an operation of, or on, the machine 100. When suchcontrol signals are received by the Vehicle ECMs 124, such Vehicle ECMs124 then implement the instructions/commands of the control signal fromthe AECM 134.

By way of explanation, the Vehicle ECMs 124 implement control signalsfrom the AECM 134 that are based operator input to the ROS 164 but theyalso monitor and regulate certain functions on the machine 100. Thus,advanced machine control features, such as traction control, ridecontrol, power control and the like, will still operate while themachine 100 (FIG. 1) is under teleremote, semi-autonomous or autonomouscontrol by the operator and receiving control signals from the ROS ECM186 (FIG. 3) that are based on operator input to the input devices 246,248. For example, the AECM 134 (FIG. 2) may transmit a control signalthat instructs the machine ECM 172 to apply braking. While the machineECM 172, in response to the control signal, may actuate the brakes, themachine ECM 172 may still continue to implement power management (anadvanced machine control feature). In another scenario, the AECM 134 maytransmit a control signal that instructs the machine ECM 172 to steerthe wheels 106 toward the right. The machine ECM 172 may generate andtransmit, in response to such control signal, a control signal to theimplement ECM 176 to actuate steering of the wheels 106 (by theimplement ECM 176) toward the right but still continues to generatecontrol signals that implement traction control (an advanced machinecontrol feature) on the machine 100.

The AECM 134 may receive data from one or more Vehicle ECMs 124, thefirst display 146, the VHUS 148 and the positioning system 150 via thesecond switch 208 (the local router 162 and the first switch 206) of theEthernet LAN 128. The AECM 134 is also configured to receive datacaptured by various sensors 220 disposed on the machine 100 (e.g.,linear position sensors 220 a, the first and second IMUs 212, 216,engine and transmission speed sensors 220 b, 220 c, and the like). TheAECM 134 receives data (via the Ethernet LAN 128, the first CAN 130 orsecond CAN 132) from the linear position sensors 220 a and uses suchdata to determine the steering articulation angle and the implement liftand tilt angle. The AECM 134 receives data from the first IMU 212 (inone embodiment, via the second CAN 130) and the second IMU 216 (in oneembodiment, via the second CAN 132) and uses such data to determineacceleration and machine inclination angle. In an embodiment, the firstIMU 212 may be disposed on the engine end-frame 109 and the second IMU216 may be disposed on the non-engine end frame 111. The AECM 134receives data from the engine and transmission speed sensors 220 (b-c)to determine engine revolutions per minute (RPM) and machine groundspeed. The AECM 134 is configured to determine machine direction,implement position and machine mode. In teleremote, semi-autonomous orautonomous modes, when the remote operator is controlling the machine,the maximum available gear may be restricted. For example, the machine100 may be limited to operation in first gear. The AECM 134 is alsoconfigured to control certain (machine 100) functions, such as groundcondition monitoring, automatic steering/turning (when activated by theoperator) etc. The AECM 134 is also configured to forward certainoperator requests for advanced control features from the ROS ECM 186 tothe appropriate Vehicle ECMs 124 (e.g., automatic dig position). Whenautomatic dig position is requested/enabled, the depth and loading ofthe bucket 114 (ground engaging work tool) in a material isautomatically controlled by the machine 100 in response to aproductivity value. The AECM 134 may also be configured to provide datato payload type systems that analyze load times, number of passes andpayload data to determine efficiency optimization. Similarly, the AECM134 may be configured to support tire monitoring, as well.

The AECM 134 is also configured to transmit data via the localtransceiver 126, including feedback information, to the ROS ECM 186. Inaddition, the AECM 134 is configured transfer control of the machine 100to the LOS operator console 184 for machine recovery purposes, when themachine ECM 172 detects that signals are being received from both theAECM 134 and the LOS operator console 184, as discussed later herein.

The environment monitoring system 136, generally, determines andtransmits data based on the environment in which the machine 100operates. More specifically, as shown, the environment monitoring system136 includes one or more internet protocol (IP) cameras 198. In anembodiment, the environment monitoring system 136 may further includethe microphone 200. In another embodiment, the environment monitoringsystem 136 may further include one or more LADARs 202. As shown in theexemplary embodiment of FIG. 3, each of the one or more IP cameras 198,the microphone 200, and the one or more LADARs 202 are connected to thefirst switch 206, which may then provide data collected from suchdevices to be transmitted to, for example, the AECM 134, the localrouter 162, the local transceiver 126 and the ROS ECM 186.

The one or more IP cameras 198 are mounted on the machine 100 and allowthe operator to monitor the machine 100 and its surrounding environment.The one or more IP cameras 198 are configured to provide one or moreviewing perspectives from the machine 100 (e.g., a front-facing viewingperspective, a rear-facing viewing perspective, etc.). Accordingly, eachof the one or more IP cameras 198 may be positioned, relative to themachine 100, to provide a specific viewing perspective. For example, afirst and second of the plurality of IP cameras 198 are positioned toreplicate the field of view an operator would see looking forward andrearward while in a cab 118 of the machine 100. A third IP camera mayprovide a view forward on the left hand side of the front of the bodyframe 104 to assist with tramming around corners and loading anddumping. A forth IP camera 198 may be positioned either on the righthand side of the front of body frame 104, the right hand side of therear of the body frame 104 or as a camera that engages when the machine100 is moving backwards (in reverse).

The IP cameras 198 are configured to generate video data associated withviewing perspectives of the machine 100. In an embodiment, the IPcameras 198 provide video data via high definition video streams thatare transmitted to the first interface device 226 (FIG. 3) of the ROS164. Each IP camera 198 (FIG. 2) is configured to transmit such videodata via a video stream to the local transceiver 126 via the EthernetLAN 128 (more specifically, the first switch 206, the local router 162and the associated communication channels 204). The AECM 134 candetermine, upon connection of an IP camera 198 to the first switch 206,the physical location in relation to the machine 100 that the IP camera198 occupies and the IP assignment of the IP camera 198. This isaccomplished via DHCP IP address assignment provided by the first switch206. This reduces the requirement for manual configuration of each IPcamera 198 and the possibility of error in the determination ofpositional mounting.

The microphone 200 is configured to capture audio data associated withthe machine 100, and the work area adjacent to the machine 100. Suchaudio data may be captured by the microphone 200 and transmitted in avideo stream from one of the IP cameras 198 to the local transceiver 126via the first switch 206 and the local router 162, and then istransmitted by the local transceiver 126 to the ROS 164 (FIG. 3). Theterm video stream, as used herein, includes video data, and may alsoinclude audio data.

The one or more LADARs 202 (FIG. 2) are sensing devices used todetermine positioning data associated with the machine 100. LADAR 202 isa radar-like remote sensing technology that measures distance byilluminating a target with a laser and analyzing the reflected light.The one or more LADARs 202 are configured to generate positioning dataassociated with the machine 100, which is used in guiding/operating themachine 100 in, for example, an autonomous or semi-autonomous mode (theLADARs 202 are not required for teleremote operation of the machine100). In some examples, the one or more LADARs 202 may generatepositioning data based on specific placements of the LADARs 202 on themachine 100 (similar to the IP cameras 198, the first switch 206 willassign DHCP addresses to the LADARs 202 based on their physical locationon the machine 100—this reduces the need for manual configuration) orperspectives of the machine 100. The determined positioning data istransmitted to the local transceiver 126 via the first switch 206 andthe local router 162 and from thereto the ROS 164 (FIG. 3).

The RSM 138 (FIG. 2) is disposed on the machine 100 and is in operativecommunication with the AIS Monitoring System 166 (FIG. 3). The RSM 138is configured to receive a safety control signal from the AIS MonitoringSystem 166 (FIG. 3) (more specifically, the machine shutdown module 264of the AIS Monitoring System 166) when the machine is being operated inteleremote mode, a semi-autonomous mode or an autonomous mode. The RSM138 (FIG. 2) then sends to the machine ECM 172 and the transmission ECM174 a control signal indicating that the safety control signal is beingreceived. The RSM 138 also receives digital inputs from the machine ECM172 and the transmission ECM 174 as a feedback to authenticate thereception of the control signal. If the RSM 138 ceases to receive thesafety control signal from the machine shutdown module 264 of the AISMonitoring System 166 (FIG. 3), no further control signal is sent by theRSM 138 (FIG. 2) to the machine ECM 172 and the transmission ECM 174;this results in the machine ECM 172 and the transmission ECM 174immediately shutting down the machine 100.

The LOS transceiver 160 is disposed on the machine 100 and is inoperative communication with the second CAN 132 and the (off-board) LOSoperator console 184. In one embodiment, the LOS transceiver 160 is inwireless communication with the LOS operator console 184. The LOStransceiver 160 receives control signals from the LOS operator console184 that are based on operator input entered into the LOS operatorconsole 184. These received control signals are transmitted by the LOStransceiver 160 to one or more of the Vehicle ECMs 124 via the secondCAN 132 and control the operation of the machine 100.

Each keypad 158 may be disposed on the machine 100 and is configured toreceive/accept user input and to transmit control signals based on theuser input, via the second CAN 132 to the AECM 134 or the appropriateVehicle ECM 124. For example, a control signal may be sent from thekeypad 158 directly to the transmission ECM 174 to activate thetransmission 107 or to turn on/off a parking brake, or may be sent tothe implement ECM 176 to activate the lift arms/implement or to activatehigh/low beam lights on the machine 100. A control signal may be sent(based on user input to the keypad 158) to the transmission ECM 174 andthe machine ECM 172 that selects/deselects remote status for the machine100.

The autonomous control switch 282 may be disposed on the machine 100 andis configured to select/deselect autonomous status for the machine 100.

By way to explanation, if remote status and autonomous status are both“off” or not selected, the machine 100 is placed in manual mode and maybe operated manually by an operator in the cab 118. If remote status isselected but autonomous status is not selected, the machine 100 isplaced in LOS mode and will only operate under the control of the LOSoperator console 184. If remote status is not selected but autonomousstatus is selected, the machine 100 will not operate. If remote statusand autonomous status are both “on” or selected, the machine 100 willoperate in teleremote mode, semi-autonomous mode, autonomous mode or LOSmode.

An indicator light 284 may be disposed on or near the rear of the cab118. In one embodiment, the indicator light 284 may be a green light.

On or more machine strobe light assemblies 144 (FIGS. 1-2) may bepositioned on the outside of the machine 100 to indicate machine mode.In one embodiment, the machine strobe light assemblies 144 may indicate1.) manual mode, 2.) LOS mode or 3.)teleremote/semi-autonomous/autonomous mode. In one embodiment, a machinestrobe light assembly 144 may be disposed on the front of the machine100 (the front machine strobe light assembly 144 a) to provide 180°visibility when viewed from the front half of the machine 100. In suchan embodiment, the front machine strobe light assembly 144 a ispositioned to not be visible in any IP camera 198 views. A machinestrobe light assembly 144 may be disposed on the rear of the machine 100(the rear machine strobe light assembly 144 b). The rear machine strobeassembly 144 b may be disposed on the machine to provide 180° visibilitywhen viewed from the rear half of the machine 100 without being visiblein any IP camera 198 views. Each of the machine strobe light assemblies144 include a first light 286 and a second light 288, the second light288 emitting a different colored light than the first light 286. In theexemplary embodiment described below, the first light 286 is an amberlight and the second light 288 is a red light.

Each machine strobe light assembly 144 is configured to provide a visualindication of which mode (manual mode, LOS mode,teleremote/semi-autonomous/autonomous mode) the machine 100 is operatingin. This involves the use of the indicator light 284, and the firstlight 286 (amber light) and the second light 288 (red light) of themachine strobe light assemblies 144 in various combinations. When themachine 100 (FIG. 1) is being operated in manual mode (operator in thecab 118 on the machine 100 and the remote status and autonomous statusare both off), the indicator light 284 (green) and the first light 286(amber) and the second light (red) 288 of the machine strobe lightassemblies 144 are not illuminated.

When autonomous status is on/off and remote status for the machine 100is initially selected via the keypad 158, the indicator light 284(green) may flash (e.g., at 2 hertz) during the request for selection ofremote status, the first light 286 (amber) and the second light 288(red) (FIG. 1) are not illuminated. Once the remote status selectionrequest is granted, the indicator light 284 (green) may flash in apulsed fashion; the first light 286 (amber) and second light 288 (red)are not illuminated. Once the machine 100 (FIG. 1) is being run in LOSmode by an operator using the LOS operator console 184 (FIG. 3), theindicator light 284 (green) (FIG. 1) may be illuminated in a constantmanner and the first light 286 (amber) and the second light 288 (red)are not illuminated.

When remote status is selected via the keypad 158 and autonomous control(semi-autonomous control or entirely autonomous control) is initiallyrequested by an operator through selection of the autonomous state viathe autonomous control switch 282, the indicator light 284 (green)flashes (e.g., at 2 hertz) and the first light 286 (amber) and thesecond light 288 (red) in the machine strobe light assemblies 144 flashfor a period of time (for example 5 seconds). After the period of time,the second light 288 (red) will turn off, but the first light 286(amber) and the indicator light 284 (green) remain flashing. This isindicative of the AIS Monitoring System 166 (FIG. 3) not yettransmitting a safety control signal to the RSM 138 (FIG. 2) of the MAS120. (If the AIS Monitoring System 166 is not transmitting a safetycontrol signal, the first light 286 (amber) (FIG. 1) is flashing and thesecond light 288 (red) is not illuminated.) If the AIS Monitoring System166 is transmitting a safety signal, the second light 288 (red) flashesand the first light 286 (amber) is not illuminated. Thus, in thescenario above, when the RSM 138 (FIG. 2) receives the safety controlsignal, the RSM 138 will send a control signal to the machine ECM 172 sothat the second light 288 (red) (FIG. 1) will flash and the amber light145 b will not be on; the indicator light 284 (green) will remainflashing. If the ROS ECM 186 does not subsequently request control ofthe machine 100, then the indicator light 284 (green) continues to flash(at, for example, 2 hertz). If the ROS ECM 186 does subsequently requestcontrol of the machine 100 (for the teleremote, semi-autonomous orautonomous mode), the illumination of the indicator light 284 (green)will begin pulsing. Once the machine 100 is operating under the controlof the ROS ECM 186, the indicator light 284 (green) is illuminated in aconstant manner.

The first display 146 (FIG. 2) is disposed on the machine 100. Forexample, the first display 146 may be disposed in an operator cab 118(FIG. 1) of the machine 100. The first display 146 (FIG. 2) may receivefrom the AECM 134, and display, various machine fault codes, machinemodes, various functions and diagnostics. For example, the first display146 may display machine mode information and may accept operator inputfor transmission to the AECM 134 or the machine ECM 172. For example,the first display 146 may accept operator input that selects a strobepattern and then transmit that input to the machine ECM 172. The firstdisplay 146 may display information indicating whether the signals fromthe transmission ECM 174 and the machine ECM 172 to the RSM are active,whether the autonomous status is selected/deselected by the autonomouscontrol switch 282, whether the remote status is selected/deselected onthe keypad 158, whether remote status is pending or active, whether theROS ECM 186 or (a controller associated with) the LOS operator console184 has reservation of the machine or whether the machine is unreserved,the current state (on, off, flashing etc.) of the indicator light 284,or the first and second lights 286, 288, the current position indicatedby the steering and implement sensors 220 a diagnostics on certainrelays in the machine 100 and whether the power saving mode is on/off.The power saving mode turns off various components on the machine 100,including some of the Vehicle ECMs 124 and LADARs 202 to reduce batteryconsumption while still keeping the Ethernet LAN 128 and the RSM 138active. In some embodiments, power saving mode can be deactivated when amachine 100 is operated in teleremote, semi-autonomous or autonomousmode.

The VHUS 148 provides detection of an impeding or abnormal condition inany of the machine's 100 systems and an operator notification to eithermodify operation of the machine 100, schedule maintenance, or perform asafe shutdown of the machine 100. VHUS 148 also may provide productionand performance information and may record load time, travel loaded,dump time, and travel empty, along with delay times. Data from the VHUSmay be transmitted to the AECM 134 and to the ROS 164 (FIG. 3).

The positioning system 150 (FIG. 2) is disposed on the machine 100. Thepositioning system 150, in some embodiments, may include a seconddisplay 152, and may be in operative communication with the secondswitch 208 via the Ethernet LAN 128. The positioning system 150 isconfigured communicate fleet management information such as position andother machine 100 related information to off-board fleet managementsystems (and the like) that provide real-time machine 100positioning/tracking, assignment and productivity management for afleet. The second display 152 may be in operative communication withsuch off-board fleet management systems, and may be configured todisplay tracking, assignment and productivity and other machine 100related information.

The TMS transceiver 218 is configured to receive tire pressure andtemperature data associated with each wheel 106 and to transmit suchtire pressure and temperature data to the VHUS 148 and the first display146 via the first CAN 130. The TMS transceiver 218 is also configured totransmit such tire pressure and temperature data to the AECM 134 via thefirst CAN 130. Such data is then transmitted from the AECM 134 to theROS ECM 186 (FIG. 3) for display on a first and second interface 226,228.

The ROS 164 (FIG. 3) is configured to remotely operate one or moremachines 100 employed at a worksite. The ROS 164 is remotely locatedfrom the machines 100. In some embodiments, the ROS 164 may be disposedat a location underground (but outside of the work area of the machine100). In other embodiments, the ROS 164 may be located near or above thesurface of the mine. The ROS 164 enables the operator to control themachine 100 (FIG. 1) functions as if the operator was in the cab 118disposed on the controlled machine 100. For example, the operator canremotely control functions such as the speed and direction(forward/reverse), steering, implement controls, lights and horn.

The ROS 164 may include a fire suppression switch 254. The firesuppression switch 254 is configured to provide the worksite with a safeguard against possible fires and is in operative communication with theROS ECM 186.

The AIS 232 (FIG. 3) includes an AIS shutdown switch 250, an AIS resetswitch 252, a first AIS shutdown programmable logic controller 256 and asecond AIS control programmable logic controller 258. The AIS shutdownswitch 250 is configured to provide a safety feature at the worksitewhere the machine 100 is employed and is in operative communication withthe AIS shutdown programmable logic controller 256. The AIS reset switch252 is configured to reset the safety feature at the worksite back tooperating conditions and is operatively associated with an AIS shutdownprogrammable logic controller 256.

The AIS shutdown switch 250 and the AIS reset switch 252, may both be incommunication with the off-board router 260 via the AIS shutdownprogrammable logic controller 256 and the AIS control programmable logiccontroller 258. In this manner, the off-board router 260 is also incommunication with the AIS Monitoring System 166 via the off-boardnetwork switch 262.

The AIS Monitoring System 166 ensures that the work area the machine 100is operating in remains isolated from personnel and equipment. A pair ofbarriers may be set up at each entrance to the work area of the machine100. One barrier may prevent personnel from entering the work area, thesecond may prevent the remotely operated, or an autonomously operated,machine 100 from escaping the work area. The AIS Monitoring System 166may be located off-board of the machine 100 and may include an at leastone machine shutdown module 264 in communication with an at least onebarrier control panel 266, both of which are in communication with theoff-board network switch 262. The at least one barrier control panel 266is further in communication with a machine barrier switch 268, and apersonal barrier switch 270 and barrier sensors disposed on or adjacentto barriers. The AIS Monitoring System 166 monitors signals from barriersensors disposed adjacent to each barrier, as well as the machinebarrier switches 268, and the personal barrier switches 270 at eachbarrier and at the ROS 164. Barrier sensors may include lights curtains,LADARs, proximity switches mounted to gates, and fixed tension switchesattached to lanyard cables.

When all signals are satisfactory (e.g., at the AIS shutdown switch 250,machine barrier switches 268, personal barrier switches 270, the barriersensors etc.), the machine shutdown module 264 transmits a safetycontrol signal to the machine 100, more specifically to the RSM 138 thatthen transmits a control signal to the machine ECM 172 and thetransmission ECM 174, that allows the machine 100 to operate. If abarrier sensor, machine barrier switch 268, personal barrier switch 270or AIS shutdown switch 250 has been triggered or the signal from such islost, the machine shutdown module 264 ceases to transmit the safetycontrol signal to the RSM 138 and the RSM 138 ceases to transmit thecontrol signal to the machine ECM 172 and the transmission ECM 174. Themachine ECM 172 and the transmission ECM 174 immediately shut down themachine 100 if the control signal from the RSM 138 is lost or ceases.

If both signals from the LOS operator console 184 and the AECM 134 aresensed by the machine ECM 172, the machine ECM is configured to givepreference to (act upon) the signals from the LOS operator console 184.The AECM 134, in this situation, is configured to relinquish control ofthe machine 100 to the LOS operator console 184. This is to allow themachine 100 to be recovered from a situation/location (for example, adangerous location) via use of the LOS operator console 184, without anoperator having to approach the machine 100 to change the operation modeto the LOS mode. For example, in a scenario where the machine isoperating in autonomous mode (remote status is selected and autonomousstatus is selected) and an urgent need arises (for example, the machine100 moves onto unsupported ground) for the operator to take control ofthe machine 100, while in line of sight of the machine 100, the operatorcan take control of the machine via the LOS operator console 184 withouthaving to approach the machine to deselect the autonomous status on theautonomous control switch 282 on the machine.

The received control signals may alsobe generated by the AIS Monitoring System 166. The off-board transceiver168 may receive from the local transceiver 126 data from the MAS 120(e.g., images or video of the work area in which the machine 100 ispositioned/operating captured by the IP cameras 198, audio captured bythe microphone 200, and positional and distance measurement informationfrom by the LADAR 202 related to the machine 100 and the work areaadjacent to the machine 100, machine operational or health related data,and other information).

The ROS ECM 186 is also incommunication via the off-board LAN 170 with the first and second inputdevices 246, 248, the fire suppression switch 254, and a seat sensor 278for detecting an operator in the seat 224 of the ROS 164.

In an embodiment, the seat sensor 278 (FIG. 3) is disposed integrallywith the seat 224 (FIG. 5) of the ROS 164 (FIG. 3) and is configured todetect when an operator has moved out of the seat 224 such that, upondetection, the ROS ECM 186 is configured to automatically lock down thefirst and second input devices 246, 248; the RSM 138 may bring themachine 100 to a safe state (shut it down) as a result of the triggeringof the seat sensor 278. As non-limiting examples, the seat sensor 278can be a pressure sensor, an analog-voltage sensor, and any otherwell-known sensors in the art.
